<p>Almost all electronic components require a DC power supply at present days. The needs of DC power supplies from low voltage scales, medium voltages such as generators, to high voltage scales for high voltage electricity transmission. The improvement of PI controller performances is presented in this paper. The adaptation gains improve transient response of DC-DC Boost Converter several operating conditions. Massachusetts Institute of Technology (MIT) rule is applied as an adaptive mechanism to determine the optimal control parameters in some conditions. The used adaptive control technique is Direct Model Reference Adaptive Control (MRAC), this method as able to control system in some various input voltage. The proposed method has a stable response and able to reach the model reference smoothly. However, the response of the system has instantaneously overshoot and follows the response back of model reference. The responses of proposed controller have short period of rise time, settling time, and overshoot.</p>

This paper presents a study of the Doubly Fed Induction Machine (DFIM) powered by two matrix converters; one connected to the stator windings and the other connected to the rotor windings. First, the mathematical model of DFIM and those of the matrix converters are developed. Then, the vector control technique is applied to the DFIM. Fuzzy logic is used in order to automatically adjust the parameters of the PI controller. The performance of this structure under different operating conditions is studied. Particular interest is given to the robustness of the fuzzy logic based control. The operation of the DFIM under overload conditions is also examined.  Simulation results obtained in MATLAB/Simulink environment are presented and discussed.

Converter Design

Abstrak— Paper ini menampilkan desain double boost converter yang mempunyai kemampuan menggandakan tegangan dua kali lipat berturut  turut beban DC yang menghasilkan tegangan output tambahan atau cadangan suplai pada beban. Pada umumnya double boost converter ini adalah konverter daya DC to Dc meningkatkan tegangan dari input (pasokan) ke output (beban) di desain menunjukkan bahwa dengan inputan sumber AC yang di searahkan terlebih dulu dengan converter penyearah berfungsi untuk mengatur kecepatan motor BLDC. Untuk pengontrolan pada beban motor menggunakan PI controller ( Proportional Integrator) dimana  parameter PI controller diperoleh dari trial eror. PI controller juga berfungsi memperbaiki gelombang keluaran dan kecepatan motor BLDC. Kata kunci : Motor BLDC, Double Boost Converter, PI controller. Abstract— This paper features a double boost converter design that has the ability to double the successive voltage in a DC load which results in an additional output voltage or supply reserve at load. In general, this double boost converter is a DC to Dc power converter increasing the voltage from input (supply) to output (load) in the design shows that the input AC source is aligned first with the rectifier converter to regulate the speed of the BLDC motor. To control the motor load using a PI controller (Proportional Integrator) where the PI controller parameter is obtained from the trial error. The PI controller also functions to improve the wave output and speed of the BLDC motor.
